REPORT OF THE STATE PALEONTOLOGIST 1900 19 



There is a total of 3134 now listedi. In addition to these are the 

 following groups to be considered, among all of which the museum 

 possesses some type specimens: graptolites; blastoidea; echin- 

 oidea; cystoidea; asteroidea; corals; bryozoa; Crustacea; fishes; 

 plants. 



The method which has been adopted in the preparation of this 

 list is that of a separate entry for each specimen illustrated, so 

 that the total number of entries will indicate the total number 

 of such typical epecimens. 



Loeality record of fossils. A year ago I communicated with my 

 report the list of localities from which fossils have been obtainedi 

 in the state, believing that it would be of practical use if made 

 accessible to students of paleontology, and I submit herewith a 

 continuation of that record, being the additional localities entered 

 during the past year. Some of these numbers represent material 

 which was collected some years ago by field workers but came into 

 the hands of the department only recently. The hiatus which ap- 

 pears in the numbering arises from the desirability of reserving 

 consecutive locality numbers for the material collectedi in central 

 New York, where investigations are still in progress. 



Memoir on the genera of the rugose corals. The work in prepara- 

 tion of the memoir on fossil corals has been steadily carried for- 

 ward; and at the present time I report that the descriptive mat- 

 ter has been largely prepared, in a preliminary form, and is ready 

 for careful and! detailed review. The draftsman, Mr Simpson, has 

 completed nearly all the necessary drawings, 36 plates have 

 been arranged, and of these 24 have been drawn on stone by the 

 lithographer, Mr Ast, and are ready for printing. The plan of 

 the memoir contemplates at the present a taxonomic study 

 of the generic characters of the rugose corals, as we have found 

 it impracticable with our present collections and for other ex- 

 cellent reasons, to contemplate at this time the investigation of the 

 entire group of fossil corals of the New York formations. The 

 subject involved in these investigations is one of some difficulty, 

 and the work must in consequence advance cautiously and with 

 deliberation. I hope, however, to report the matter soon in con- 

 dition for publication.
